Doctor insights on:
Fovea is Central : The macula is the central part of the retina that gives us our ability to read and see detail. The very center region of the macula is called the fovea. It is responsible for our most acute vision. If it is injured or damaged we usually cannot read letters and images become distorted or "blocked." the fovea is the central retina, so yes it is connected. ...Read moreSee 1 more doctor answer
Yes: Most common procedure to repair a retinal detachment resulting from a macular hole is a vitrectomy (remove the fluids from the back of the eyeball), replace it with a gas, and position the patient face down for some period of time (sometimes weeks) to allow the hole to close and the detachment to resolve. Most macular holes do not cause a detached retina, but many require a similar operation. ...Read moreSee 1 more doctor answer
Lt.eye mac.pucker.Corrected vision 20/40 µpsia.Amsler grid nl.Corrected vision 20/40.Age 69.Could the macuar pucker cause micropsia?Rt. eye20/30.
Micropsia: Yes, it can if the macular pucker is severe enough. Micropsia is a condition in which objects are perceived to be smaller than they actually are. Micropsia can be caused by optical factors (such as wearing glasses), by distortion of images in the eye (such as optically, via swelling of the cornea or from changes in the shape of the retina such as from retinal edema,macular degeneration, and more ...Read more
Progressive macular pucker 20/30 vision, distortion & glaucoma. Visual fIeld good,nerve damage 30-45%.Would vitrectomy cause glaucoma to progress?
Possible: Vitrectomy and glaucoma may have an association. It is suspected that glaucoma occurs more often in patients who have had vitrectomy and subsequent cataract surgery. An ongoing clinical trial is aimed to answer this question with more clarity. PROVE Study. http://www.aaojournal.org/article/S0161-6420(14)00344-3/references AND https://clinicaltrials.gov/ct2/show/NCT01162356 ...Read more
Hemi-field loss: Is usually due to a pathology posterior (behind) to the eye itself. A lesion or area of pathology will usually be located from the area of the pituitary gland (approx. just forward of central brain) where the optic nerves cross to anywhere along the optic radiation ending at the occipital lobe (portion of the brain at the lower back of the skull). An MRI or CT can usually identify the cause. ...Read more
Maybe: The fovea is the most sensitive part of the eye, responsible for sharp detail vision. Macular translocation surgery moves the fovea to another part of the eye in cases of certain macular diseases, but the success rate is mixed, and the surgery is risky. Discuss all options with your ophthalmologist. ...Read moreSee 2 more doctor answers
The photosensitive cells (rods and cones) in the retina are most densely packed in the fovea. What is a fovea?
Central visual pit: The fovea is an anatomical pit in the center of the macular area at the back of the eye. It is a densely packed net of cones and is the part of the retina which sees the finest detail and much of the color. It is easily seen as a depression in retinal scans and as a sharp highlight with the ophthalmoscope. Be thankful for yours as it is why you can read this message. ...Read more
How progressive is unilaterlal macular pucker? Corrected vision in that eye is 20/40.Opposite eye no pucker,corrected vision 20/30.Age 69.
Epiretinal membrane: Macular pucker or Epiretinal membrane is caused in many conditions eg. Trauma, Vitreius or Retinal detachment, Diabetes or Retinal vascular episodes Condition can progress to Macular hole and cause visual distortion. Surgical treatment is Vitrectomy and excision if any tension strands. Surgery us not recommended till vision is 20/200! Or worse. You have relatively good vision and no distortion ...Read moreSee 2 more doctor answers
No: Anything causing a deposit anywhere on the cornea is termed an opacity - most due to a specific injury such as a foreign body or ulcer of the cornea after healing. Corneal dystrophy is more generalized throughout the cornea affecting one or another layer, some inherited and others like the condition fuch's, which is acquired. See your corneal specialist ophthalmologist to sort this out. ...Read more
Nerve fiber pattern: Bitemporal hemianopia is the classic later stage vision pattern in advancing pituitary tumor. Generally the central fibers, which carry the best acuity are affected later in the condition. A great deal of vision loss would have to be ignored by someone with this condition before the nerve fibers for the central acuity start to drop out. ...Read more
Is this optical migraine? Flashing zig-zag @periphery of vision. Printed words distorted/stretched at periphery, like they're moving & fading in/out.
Yes: The vitreous jelly that fills the eye and attaches to the back wall of the inside of the eye (the retina) will detach from the retina with age (posterior vitreous detachment). At that time or days/weeks later a retinal tear or detachment may or may not occur as well. The latter conditions require urgent treatment before blindness ensues. A vitreous detachment is not treated. ...Read moreSee 2 more doctor answers
Many possible causes: As we age, the vitreous may pull away from its attachment to the retina at the back of the eye. If the vitreous pulls hard enough to tear the retina in one or more places, fluid may pass through, lifting the retina off the back of the eye, causing it to detach. Some risk factors for detachment are: nearsightedness, trauma to the eye or a family history of retinal detachment. ...Read more
Possibly: The fovea is the most delicate part of the eye. 90% of all vision fibers connect to this tiny area. There are new amazing surgeries to repair conditions like macular holes that once led to blindness, & treatments for wet macular degeneration that would affect the fovea. However, mechanical injury, solar, laser, or welding burns to the fovea would probably be beyond repair w/ current technology. ...Read moreSee 1 more doctor answer
